Abstract
This application relates to a fastener, a fastener monitoring system, and a child carrier. The fastener includes a male buckle, a female buckle, and a control circuit. The fastener has a locked state in which the male buckle is snap-fitted to the female buckle and an unlocked state in which the male buckle is separated from the female buckle. The control circuit is disposed on the male buckle and/or the female buckle. The control circuit includes a wireless communication module. In response to the fastener being in the locked state, the control circuit controls the wireless communication module to transmit a wireless signal.
Claims18
A fastener, comprising:
- a male buckle;
- a female buckle configured to be snap-fitted to the male buckle;
- and
- a control circuit disposed on at least one of the male buckle or the female buckle, the control circuit comprising a wireless communication module,
- wherein the fastener has a locked state in which the male buckle is snap-fitted to the female buckle and an unlocked state in which the male buckle is separated from the female buckle, and when the fastener is in the locked state, the wireless communication module transmits a wireless signal,
- wherein the control circuit further comprises a control switch, responsive to the fastener being switched between the locked state and the unlocked state, the control switch is switched between turn-on and turn-off, and the wireless communication module transmits the wireless signal in response to the control switch being turned on,
- wherein the female buckle has a slot, the male buckle has an inserting portion, and the control switch has a trigger portion located in the female buckle,
- wherein the female buckle is provided with a driving member and a sliding locking block configured to lock the inserting portion,
- wherein the driving member comprises a return elastic piece located in the female buckle, the trigger portion is located on a moving path of the middle portion of the return elastic piece, a middle portion of the return elastic piece is pressed by an end portion of the inserting portion of the male buckle, an end of the return elastic piece abuts against an outer side of the sliding locking blocks, so as to cause the sliding locking block to maintain at a position where the male buckle is locked, and
- wherein in response to the inserting portion of the male buckle being inserted into the slot of the female buckle to cause the fastener to switch from the unlocked state to the locked state, the middle portion of the return elastic piece is pushed by the male buckle to trigger the trigger portion, so as to cause the control switch to be turned on.
